Back to Stress & RelaxationWhy this matters
Stress, anxiety, burnout and depression can feel alike and can happen together. They are not the same thing. Stress is a normal response; the others range from a recognized work-related syndrome to medical diagnoses. This page explains the differences in plain terms. It cannot tell you which one you have. The NHS advises against self-diagnosis because anxiety, fear or panic can also be a symptom of several health conditions. [1]Side by side
| Term | What it means | Source note |
|---|---|---|
| Stress | The physical or mental response to an external cause, which may be brief or repeated. It often goes away when the situation is resolved. [2] | Not a diagnosis |
| Anxiety | The body's reaction to stress; it can stay even when there is no current threat. [2] Occasional anxiety is normal. [3] | Normal feeling |
| Anxiety disorders | Anxiety that does not go away, is felt in many situations and can get worse over time. [3] Types include generalized anxiety disorder, panic disorder, social anxiety disorder and phobia-related disorders. [3] | Medical diagnosis. See Anxiety disorders |
| Burnout | In the WHO's international classification (ICD-11), a syndrome from chronic workplace stress that has not been successfully managed, with exhaustion, mental distance from the job and reduced efficacy. It is described as an occupational phenomenon, not a medical condition. [4] | See Burnout |
| Adjustment disorder | Described in a primary-care review as an extreme emotional reaction to a stressor. [5] | Medical diagnosis. See Adjustment disorder |
| Depression | Different from ordinary low mood: it can cause severe symptoms that affect how you feel, think and handle daily activities such as sleeping, eating or working. [6] | Medical diagnosis |
| PTSD | Symptoms that last a long time after a traumatic event and interfere with daily life. [7] | Medical diagnosis. See Trauma-related stress and PTSD |
Where they overlap
- Stress and anxiety disorders. Anxiety disorder symptoms often get worse during stressful periods such as illness, exams or family conflict. [8]
- Anxiety and depression. Depression is among the conditions that can occur alongside generalized anxiety disorder and panic disorder. [8][9]
- Burnout and depression. A review of 92 studies found that the line between burnout and depression is "conceptually fragile" and that research has not settled whether burnout is distinct from depression. [10] Treat that as an open question in the research, not a reason to dismiss burnout. If your mood is low most days, a professional should assess for depression.
- Long-term stress and health. Long-term stress has been linked to depression and anxiety. [11]
Things that can look like stress
Some physical conditions produce similar symptoms. For example, a provider may do a physical exam to make sure an unrelated physical problem is not causing anxiety symptoms. [8] Similarly, fatigue has many causes, including stress and depression, but also medical conditions. [12] See Why am I so tired?.How a professional sorts it out
A primary care provider can do an initial mental health screening and refer you to a psychologist, psychiatrist or clinical social worker. [13] In an assessment, the provider may ask when symptoms began, how long they have lasted, how often they occur and how they affect your life. [8] That information, not an internet checklist, is what separates ordinary stress from a diagnosis.Frequently asked questions
Is anxiety just stress?
Not exactly. Stress usually has an outside cause and fades when it is resolved. Anxiety is your reaction and can continue without a current threat. [2]
Is burnout a medical diagnosis?
In the WHO's classification it is an occupational phenomenon, not a medical condition, and it refers to the work context only. [4]
Can I have anxiety and depression together?
Yes. NIMH lists depression among the conditions that can co-occur with generalized anxiety disorder and panic disorder. [8][9]
Who can diagnose these?
A health care provider such as a primary care doctor, psychiatrist, psychologist or clinical social worker. [8]

When to get help
Seek help if stress or anxiety interferes with everyday life, causes you to avoid things or seems to be always present. [2] Get help right away if you have thoughts of suicide. In the US, call or text 988 (free, 24/7); in a life-threatening situation, call 911. [13][14] Elsewhere, use your local emergency number. See Stress and anxiety safety.
